To atZZ whom/it may. concern; J

Be it known that I, JOSEPHL'. GIROUX, a citizen of the United States, residing=at J orome, county of Yavapai, Arizona'lerritory, have invented an Improvement in Steam- Generators; and I hereby declare the following to be a full, clear, and exact-description of the same.

My invention relates to an apparatus for generating steam; and it is especially designed for the employment of a'fuel which can be continuously supplied and removed when exhausted.

My invention-is especially designed for the utilization of the hot slagfrom smelting-furnaces and the like 3' but other form's-of fuel may be employed in conjunctioniwitha gen-' erator of this deseriptiom It consists of an annular, tubular, and hori-- zontally revoluble shell having acontinuous fire-box or furnace in .the form of an: open channel from one side andmeans for continously supplying the fuel atone point and means for removing it when the" heat is exhausted.-

My invention also comprises details of construction, which will bemore fully explained by reference to the accompanying drawings, in which Figure lis a-planof my invention. Fig.2 is a vertical section on the .line 000:, Fig. 1?

Fig. 3 is an enlargedis'ection of Fig. 2. Fig.1 4 is a portion o'fa planof Fig. 3. Fig. 5 is'a plan of the scraper. Fig. 6 shows adetached part of the driving:rack and-pinion.

The object of my invention-is to provide a steam-generator of large'capa'ci-ty, and I have in the present illustration 'shown'itas especially fitted for the employment'of a fuel consisting of the hot molten slagwhich is discharged'from' smelting-furnaces; and the invention therefore comprises means for continuously supplying the'slag into the peculiarly-disposed furnace of the generato-r,of revolving the generator and-its'furnace about a vertical axis, of a means for removing the slag or other fuel when exhausted, means for forming a closure for the furnace during its revolution and means for supplying water to the boiler and removingsteam therefrom.

As shown in the present drawings, my generatoris formed of short cylindrical sections "fuel.

A, .which may be made of any suitable or desired form in transverse section. In the present case I have shown these sections as cylindrical, and they are so formed and r-iveted together that when complete the generator is in the form of a large annular cylin drical' rim which is suitably supported upon a foundation with antifrictional bearings, as

at 2, and a driving-rack engaged by gears, as at 3,-or equivalent-means whereby the tubujlar shell can be revolved around its center of rotation. I

The furnace is in the form of an open horizontal channel 4,which;extends from one side of the shell into the interior, as plainly shown in the cross-section. extends all the Way around the periphery of the annular shelland-is here shown as open- This furnace-chamber ing toward the outside for convenience in this rim forming a depression in the bottom of the furnace, which serves to hold a liquid In the presentcase I have'designed to employ the hot slag discharged from smelting-furnaces, and for this purpose I have shown an inlet pipe or passage,as- 6,Which may lead from the settling tank or attachment of thefurnace, in which the metalisseparated from the slag." Theslagis delivered through this passage into the generator-furnace previously'described, and the generator is caused to revolve at a rate of speed depending upon slag will retain its heatr its size and upon the length oftime that the I It will be understood that liquid hydrocarst bon or other form of'fue'lco'uldbe usedwithgood effectin a generator of tjhis description,

the operation beingess'entia'lly'the same as in the present illustration.

In order to retain the heat within the furnace, a wall is built, as shown at 7, surrounding the generator and close to its periphery, and in order to make a close joint between the periphery of the generator and the wall,

iOO

inasmuch as the generator is here shown as being constructed of short straight sections which form a polygonal periphery, I have shown a plate of metal or other suitable material fixed to the generator above the mouth of the furnace, as shown at 8. The periphery of' this plate is made as nearly circular as possible and is designed to travel in close proximity with the wall 7, so that it does not allow any appreciable amount of heat to escape. The wall is continuous around a generator, with the exception of the points of inlet and discharge.

In order to strengthen and properly brace the generator, I have shown tension-rods 9, with turnbuckles 10 or other equivalent means for adjust-ing them. The outer ends of the rods are firmly secured to the inner periphery of the annular generator-shell, as shown at 11, and the inner ends are secured to a hub, as at 12, which is mounted and turnable upon a central pillar or standard 13.

Where hot slag is employed for a fuel in this generator, it is admitted, as previously stated, through a passage at 6, and it is removed by means of a plow 14, which is fixed so as to project into the furnace and into the pathway of the slag. This plow is suitably curved, so that it scoops up the slag as the generator revolves and forces it out of the furnace, so that it will discharge througlra mouth or chute, as at 15, and slagcars, as 16, may be run upon a track beneath the discharge to receive the waste slag, which can be then carried OE and dumped. If it is desired to raise or lower or otherwise adjust the slag-plow, it is effected by mounting it upon a frame, which is vertically adjustable by means of ascrew-shaft 17,having a handwheel or means for turning at the top and a screw turnable in the threaded sleeve or nut, which carries the frame of the slag-plow or equivalent raising or lowering device, as shown at 18. In this manner the operation of the apparatus can be made continuous as long as the fuel is supplied.

In order to supply water to an apparatus of this description, I have shown the feedwater pipe 19 as extending up through the central pillar 13, having one or more branches, as 20, extending outwardly to the shell connecting therewith at as many points as may be found desirable. Asuitable packed joint, as at 21, allows the radial portion 20 of the pipe to revolve about the stationary vertical portion 19. By a similar arrangement steam is withdrawn from the generator by means of steam-delivery pipes 22, connecting with the upper part of the boiler-shell or with steamdomes thereon, if found desirable. These pipes all lead to a common center 23, with which they connect, and this receiver connects with a main steam-delivery pipe, as at 24, which leads the steam to any point where it is desirable to use it. A turnable packed joint, as 25, allows of the movement of the branch pipes 22 with relation to the stationary delivery-pipe 24: and maintains a tight joint during the operation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
